Yuletide Bride by Kasey Stockton

When a marriage of convenience becomes inconveniently complicated…

Mercy Caldwell, the vicar’s eldest daughter, has watched her younger sisters march down the aisle while she remains resolutely on the shelf. When a chance at matrimony arrives mere hours after her youngest sister’s engagement, Mercy seizes the opportunity—and the man she’s secretly admired for years.
Colin Birchall’s grand estate is crumbling, and his aunt’s generous inheritance comes with one condition: he must be married by Twelfth Night. In Mercy, he finds the perfect candidate to meet his aunt’s exacting standards. It seems an ideal arrangement—until they’re forced to actually live together.
From differing views on marriage to clashing Christmas traditions, Mercy and Colin discover that convenience and compatibility are two very different things. But when Colin’s aunt arrives unannounced demanding proof of their love, they must convince her—and perhaps themselves—that their hastily forged union is more than just a festive facade.
